Abstract: As part of an ambitious development program at the Port of Ningbo, the People's Republic of China constructed a 694 m (2277 ft) long offshore pier structure to provide a container berth and two multipurpose berths. Pile foundations for this facility consisted of hollow, 60 cm (23.6 inch) square prestressed concrete piles in single lengths up to 57 m (187 ft) and capacities up to 3000 kN (337 tons). These piles represent some of the longest concrete piles driven to date in China. The paper describes the equipment and procedures used to install these unusually long piles, and presents the results of dynamic and static testing of instrumented piles. In addition, Wave Equation Analyses provided an essential means for evaluating the contractor's proposed pile driving equipment. Pile installation was successfully completed in February 1991, and the facility is now in operation.
